G630T Pentium vs. i3 Haswell Power

[T_Minus]

I thought I had a handful of 2nd/3rd gen i3, turns out they're both Gen 4. I was hoping to throw together a low powered 4x drive NAS but 37W idle without discs is too much.

Anyone ever compared

• How much can the Haswell motherboard+cpu take off (power-wise) than the Sandy Pentium ? (1 of the i3 is near identical rated power as the pentium)
  
• Is the G630T Pentium enough to run windows 10 browse the internet, and print? (maybe another usage)

hmm, my X9SCL with G620T (CSE-512-260B with single dimm) running pfSense idles at 27w.

Which X9 board are you running? what kind of psu are you using? what OS? how many dimms?

- SM X9SCM-F --> Supermicro | Products | Motherboards | Xeon® Boards | X9SCM-F
- 2x 8GB (what was in mobo)
- Seasonic 80+ Gold (550w or so iirc, it's the one on the bench)

C202 vs C204 is only main thing I could find between our boards? Likely another couple watts lost in mine due to power supply size too, not sure if at this low it's even 1-2W though?

I think I may have an E3 CPU or two, going to check that may determine more of my choice if I can re-use something low powered and > than that pentium.

Guessing from where I'm at chipset difference +1-2w, second dimm +1w, IPMI +5w, oversized PSU +2-3W which puts you at 8-10w over my 27w which seems about right.

Pull a dimm, if you have a smaller 80+ PSU laying around try it and how much it helps but the IPMI is always gonna up the draw....it's kind of a necessary evil unless you have 5+ boxes running and at which point it can start to get cheaper with an IP-KVM but those are a bit harder to find out the draw (most datacenters don't care about an extra 50w).

The newer generation processors are generally more efficient and have lower power consumption at idle...it really depends on what board you have laying around to pair it with.

Something is not quite right with your setup.

HP Z220 with 4 sticks of RAM, G2020T processor, 100G S3700 SSD running NAS4Free : 20 watts idle.
Add Mellanox X2 10GBE card and the consumption increases to 25 watts idle.
Measurements are at the wall with an oh-so-accurate kill-a-watt.

This is similar to what I see with a Supermicro X9SCL that I was originally going to use for my low power NAS. I haven't seem a whole lot of difference between processors at idle and I have tested Celeron, Pentium, I3 and E3's. They all drop into their lowest power mode at idle so pretty much everything is consumed outside the CPU.

The one concern I am facing with my test builds is PCIe lanes. The X9SCM is a better choice than the Z220 or the X9SCL for a low power NAS with four PCIe slots. Most are PCIe v2 and half are x4 as I recall but it gives you 10GBE + HBA plus a few slots left over.

I am torn between 1 or 2 CSE-M14TQC's or whether to bite the bullet and get a CSE-M28SACB and start transitioning to mini SAS HD.

Not sure why the X9 runs so high ?

I did just boot up a 2x 12C/24T E5-26xx v3 w/64GB SM satadom & Seasonic platinum PSU & 1x noctua fan & 2x SM 2u HSF w/proxmox and idle was 68-72w. This was with SuperMIcor fan profile 'optimal' which I think will jump +10w when fans kick in as CPU usage / disk uage / heat in general occur but it's silent even with the 2U HSF. I still may swap to 4U HSF but amazingly the 2U is very very quiet... my home AIO in a tower is louder.
